| Abstract |
Polycarbonate which is one of the types of thermoplastic has advantages such as heat resistance, impact resistance, transparency and workability. However, aromatic polycarbonates based on bisphenol A which has toxicity are not environmentally used as a product and aliphatic polycarbonates are not suitable for commercial use due to low Tg. To overcome these limitations, research on polycarbonate incorporating cyclic molecules is underway. Biomass is an industry term for getting energy by burning wood, and other organic matter like biofuels and organic starting materials. It has been classed as a renewable energy source and is possible to synthesize various furanic flatform by making 5-(hydroxymethyl) furfural (5-HMF) through hydrolysis and dehydration of certain sugars. Dimethyl carbonate (DMC) which is another environmentally friendly substance is derived from carbon dioxide and diphenyl carbonate (DPC) can be synthesized from DMC. In this study, various biomass-based polycarbonates can be synthesized by the transesterification reaction of a furan-based diol with DMC or DPC. To obtain a high molecular weight polymer, the proportions of terminal groups of -OH and -OCH3 are finely controlled. By introducing furan diol, it is possible to synthesize furan-based alkyl polycarbonate with controlled Tg and to obtain a novel biomass-based environmentally friendly polymer. |
